Haptics

expo-haptics provides haptic (touch) feedback for

On iOS, the Taptic engine will do nothing if any of the following conditions are true on a user's device:

Low Power Mode is enabled (Feature Request)
User disabled the Taptic Engine in settings (Feature Request)
Haptic engine generation is too low (less than 2nd gen) - Private API
- Using private API will get your app rejected: [[UIDevice currentDevice] valueForKey: @"_feedbackSupportLevel"] so this is not added in Expo
iOS version is less than 10 (iPhone 7 is the first phone to support this)
- This could be found through: Constants.platform.ios.systemVersion or Constants.platform.ios.platform

Installation

Terminal

→ expo install expo-haptics

On Android, this module requires permission to control vibration on the device. The VIBRATE permission is added automatically.

import * as Haptics from 'expo-haptics';

style (ImpactFeedbackStyle) - A collision indicator that on iOS is directly mapped to UIImpactFeedbackStyle, while on Android these are simulated using Vibrator. You can use one of Haptics.ImpactFeedbackStyle.{Light, Medium, Heavy}.

A Promise which fulfils once native size haptics functionality is triggered.

type (NotificationFeedbackType) - A notification feedback type that on iOS is directly mapped to UINotificationFeedbackType, while on Android these are simulated using Vibrator. You can use one of Haptics.NotificationFeedbackType.{Success, Warning, Error}.

The kind of notification response used in the feedback.

A Promise which fulfils once native size haptics functionality is triggered.

Used to let a user know when a selection change has been registered.

A Promise which fulfils once native size haptics functionality is triggered.

The mass of the objects in the collision simulated by a UIImpactFeedbackGenerator object UINotificationFeedbackStyle

Heavy - A collision between large, heavy user interface elements.
ImpactFeedbackStyle.Heavy ＝ "heavy"
Light - A collision between small, light user interface elements.
ImpactFeedbackStyle.Light ＝ "light"
Medium - A collision between moderately sized user interface elements.
ImpactFeedbackStyle.Medium ＝ "medium"

The type of notification feedback generated by a UINotificationFeedbackGenerator object. UINotificationFeedbackType

Error - A notification feedback type indicating that a task has failed.
NotificationFeedbackType.Error ＝ "error"
Success - A notification feedback type indicating that a task has completed successfully.
NotificationFeedbackType.Success ＝ "success"
Warning - A notification feedback type indicating that a task has produced a warning.
NotificationFeedbackType.Warning ＝ "warning"
